Hi-Yield Killzall Extended Control is a pre- and post-emergent weed killer, so it kills established weeds and prevents weed germination for up to 6 months! Killzall Extended is non-selective, so it's formulated to kill all vegetation. Use near fences, on paths, patios, curbs, sidewalks, driveways, around trees, shrubs, flower beds, and buildings. Weeds will wilt in a matter of days, with a complete kill of most weeds in 1 to 2 weeks. Because Killzall is a non-selective weed control, it's important to keep it off desirable plants, grasses, and vegetation or areas where you plan to plant. 32 oz. concentrated formula. Always read and follow label directions.
